LATHE-TURRET.

To all whom it may concern:

Be it known that I, FREDERICK SAMUEL THOMPSON, a citizen of the UnitedStates, and a resident of Plainfield, New Jersey, have invented certainnew and useful Improvements in Lathe-Turrets, of which the following isa specification.

My invention relates to lathe turrets and particularly to an improvedmeans for carrying secondary tools designed to operate on the work.

The accompanying drawing, and the following description set forth indetail certain mechanism embodying the invention, such disclosed meansconstituting, however, but one of various mechanical forms in which theprinciple of the invention may be used.

The drawing is a perspective view of a lathe turret embodying myinvention.

In the drawing:l, indicates the usual turret-slide adapted to movelongitudinally on the lathe bed; 2, the usual turret mounted forrotation on the slide 011 a vertical axis, the illustration showing thisturret as being of a known form provided with radial sockets forreceiving the shanks of tools, these sockets being in the horizontalplane of the axis of the lathe, and the periphery of the turret beingprovided with flat surfaces against which tools may be bolted: 3, theradial sockets of the turret: 4:, the flat peripheral surfaces of theturret: 5, a super-turret separably bolted to the top of the main turretand turning and sliding in unison with the main turret: 6, radialsockets formed in the super-turret, there being a series of thesesockets disposed in one horizontal plane of the super-turret and anotherseries disposed in a lower horizontal plane: 7, tool shanks to engagethese sockets: 8, a head on the outer end of each shank: 9, a verticalslide on each head: 10, a downwardly presenting tool carried by eachslide: and 11, screws for vertically adjusting the slides.

While the tools which will be carried by the main turret will operate onthe work as usual in the horizontal plane of the axis of the lathe, thetools carried by the super-turret may operate very considerably abovethat plane. For instance, while a tool of the main turret is operatingas usual at the central portion of a piece of work a tool of thesuper-turret may be turning a rather large flange on the piece of work.The tools of the super-turret may operate on work of con- Specificationof Letters Patent.

siderable diameter if the tools are carried in the lower sockets of thesuper-turret, but by employing the upper sockets work may be done onvery extended diameters.

Screws ll serve as means for adjusting the tools downwardly to secureproper diameter of work. The tools carried by the superturret may notonly be turning tools to operate upon the periphery of a piece of workof considerable diameter, but they may also be facing tools to operateupon the face of large work. The shank and socket system for securingthe tools in the super-turret is to be considered as typical only, andthe shanks of the tools may be secured in the sockets of thesuper-turret by any of the usual securing devices, such as set screws,clamps etc.

The tools of the super-turret may not only move forward with the generalstructure and thus turn the periphery of the work as the turret-slideadvances, but with the turret-slide held stationary a turret-tool may bemoved downward or upward in various facing operations.

The illustration assumes the main turret as having six angulartool-receiving positions, as represented by the radial sockets 3, andthe illustrated super-turret is provided with but three angular toolpositions, which are to coincide with three of the angular toolpositions of the main turret. In the illustration the main turret is ofgenerally triangular form, the extended flat surfaces 4: beingcomparatively close to the center of the turret. The tools of thesuper-turret are arranged over the centers of length of the flat sidesof the main turret, thus permitting the tools of the super-turret tooperate on work brought well toward the center of the turret.

I claim 1. A lathe turret comprising, a main turret mounted to slide androtate, a super-turret rigidly but separably secured against the mainturret and provided with a plurality of tool-receiving features in thevertical planes of tool-receiving features of the main turret, andvertically adjustable tool carrying slides carried in the tool-receivingfeatures of the super-turret, combined substantially as set forth.
